Convert PNG Images Into PowerPoint Slides Online

Manually inserting PNG images into PowerPoint — dropping each one onto a blank slide, resizing it to fit, centring it, repeating for every image — takes longer than it should. This tool skips all of that. Upload your PNG files and get back a PPTX where each image is already placed on its own slide, sized correctly, and ready to open in PowerPoint, Google Slides, or LibreOffice Impress.

In testing, a batch of 5 PNG screenshots converted to a clean, correctly sized PPTX in under eight seconds — each image centred on a separate slide with no quality loss and transparency preserved across all files.

Transfonic processes files over 256-bit SSL encryption and permanently deletes them the moment your download is ready. No account required, no watermark added, nothing stored after your session ends.

From PNG to PPTX in Three Steps

• Upload your PNG — single file or multiple PNGs at once, up to 10 files

• Each image is placed on its own slide and formatted to fit standard presentation dimensions

• Download the PPTX and open it directly in PowerPoint, Google Slides, or LibreOffice

Most conversions finish in under ten seconds. If you need the same PNGs converted into a Word document instead, PNG to DOCX handles that in the same workflow.

Who Actually Uses This Tool

PNG to PPTX is not just for people who cannot use PowerPoint. It solves a specific time problem that even experienced PowerPoint users run into regularly.

The most common workflows:

• Designers sharing mockups for review — exporting Figma, Sketch, or Adobe XD screens as PNG and converting them into a slide deck for client or stakeholder review without opening PowerPoint at all
  

• Developers creating screenshot walkthroughs — turning a set of UI screenshots into an ordered presentation for documentation, onboarding, or team demos
  

• Educators building slide content — converting diagrams, charts, or visual materials saved as PNG into presentation-ready slides
  

• Marketing teams working with infographics — repurposing PNG infographics as individual presentation slides for meetings or reports
  

• Anyone building a quick visual deck — if the content already exists as a set of PNG images, converting them is faster than building a deck from scratch in PowerPoint

What the PPTX Output Contains

Each PNG becomes one slide in the output PPTX. The image is placed at the centre of the slide, scaled to fit within standard 16:9 presentation dimensions without cropping or distorting.

You can edit the PPTX file after opening it. Overlay text, shapes and annotations for each image along with transitions/animations ability for each slide, move/delete slides, add more content and change the background of the slide. The PNG itself is on the slide, as an image object that can be resized and moved around or replaced at any point.

If you need to extract just the text content from your PNG rather than build a slide from it, PNG to text extraction is the right tool for that workflow.

How PNG Transparency Carries Into Slides

PNG supports full transparency — logos, icons, cutout graphics, and design elements with transparent backgrounds are common. When a transparent PNG is placed onto a PPTX slide, the transparency is preserved. The slide background shows through wherever the PNG has no pixels.

This is important in practice: if you are converting a logo PNG, design element or any other image where there must not be an output transparent instead of white, it will hold true for the slide. You would then adjust your slide background colour in the PowerPoint and, as a result, cleanly fit the PNG against it.

Conversely, if your graphics originally have transparency (transparent pixels), you actually want to export PNG files before converting the images to PPTX; JPG files do not support any sort of transparency.

Converting Multiple PNGs Into One Deck

Upload up to 10 PNG files in one batch. Each image becomes one slide in a single PPTX file, in the same order you uploaded them. This is the fastest way to turn a set of related images into a presentation — no PowerPoint needed at any point in the process.

Practical tip: if slide order matters, name your PNG files numerically before uploading — 01, 02, 03 and so on. Most browsers and upload interfaces sort files alphabetically, so numbered filenames give you direct control over the sequence.

For other image formats you need to include in the same presentation, the image to document converter handles JPG, WebP, BMP, TIFF, and GIF alongside PNG.

Things Worth Knowing Before You Convert

• Slide dimensions default to standard 16:9 widescreen — if you need 4:3, adjust the slide size in PowerPoint after downloading
  

• Very large PNG files may take slightly longer to process — the 20MB per file limit covers most use cases
  

• The output PPTX contains image-based slides — text visible in the PNG is not editable unless you add text boxes manually in PowerPoint
  

• Up to 10 files can be uploaded in one batch, with a total combined size of 20MB
  

• PNG transparency is preserved — transparent backgrounds carry through correctly to the slide
